Acrylic The subject is sketched on the canvas with the use of a pencil. Acrylic colours are positioned with a brush starting from the background. The shades are obtained by darkening or lightening the colour with a flat brush. The details are made with a liner and the black and white colours are used last. Watercolour To begin, the subject must be sketched on a cotton paper, delimiting the spot-shaped light spots. Then we will wet the paper with the brush leaving the light spot dry. On the wet part the watercolour colours will be applied, four or five shades of colour that will mix. Working on different layers will give strength and intensity to the colours. The details will be done at the last moment, when the paper is dry. Finally, the initial sketch pencil will be erased, the white of the paper will pop out. Oil We can sketch with the use of a pencile the subject on the canvas, we will then choose the oil colours and prepare them on the palette. The colours are directly mixed on the canvas and spread with brush or spatula. We are going to start from the background and finish with the last elements on top. Touches of light with white will be done at the end.
